What is the current model of our solar system

Biology
2 answers:
AfilCa [17]2 years ago
5 0

Answer:

The heliocentric model does accurately describe our solar system.

Explanation:

In our modern view of the solar system, the Sun is at the center, and planets move in elliptical orbits around the Sun. The planets do not emit their own light, but instead reflect light from the Sun.

This model became known as the 'geocentric' model. ... Ptolemy's model (geocentric) places the Earth at the centre of the Universe. The Sun and planets revolve in a series of circular orbits moving out from the Earth


hope that helps ! :)

Your friend brings you rocks with a thick layer of oxidation weathering, and no other visible signs of weathering. this is a clu
Vsevolod [243]
<span>A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. There are three types of weathering, physical, chemical, and biological. For the physical weathering, there are two main types. Freeze-thaw cycles and exfoliation. Obviously the freeze-thaw cycles require water and the exfoliation generally happens through thermal expansion and contraction which doesn't require water. But since neither of these mechanisms were observed, that doesn't indicate if the area was wet or dry. Biological weathering is caused by plants or animals breaking down rocks via chemical (acid) or mechanical (root growth) means. Life generally indicates the presence of water, but since this form of weathering wasn't observed, we still don't have enough data. Chemical weathering is caused by rain water reacting with the rocks to form new minerals and salts. There are several types such as acidic rainwater dissolving part of the rock, and oxidation. With this in mind, let's take a look at the available options. A moist environment because there is a greater density of oxygen in the atmosphere in the presence of water. * Yes, we need a moist environment, but the density of oxygen is fairly constant world wide regardless of how moist or dry the environment is. So this is a bad choice. A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. * Water speeds up chemical weathering of all types. So this is the correct choice. A dry environment because the increased albedo of deserts encourages physical weathering processes such as oxidation. * Yes, the increased albedo of deserts does speed up spalling, but oxidation is a CHEMICAL weathering process, not a PHYSICAL one. So this is a bad choice. A dry environment because in the absence of water oxidation is the dominant weathering process. * Water speeds up oxidation quite a bit. And since the observed oxidation is thick, there's been quite a bit of weathering. So this is a bad choice.</span>

After the ovules are fertilized what happens to the ovary
3241004551 [841]

Answer:ovary develops into fruits

Explanation: fertilization occur after the fusion of a haploid male and female gametes to give a diploid zygote. The male sperm fuses with the female egg in the ovule to give an embryo. For angiosperms the male sex cell is located in the pollen in the anther which is carried to the stigma where the female sex cell is located either of the same plant or different plant. For gymnosperms the male pollen is found in the cone from where it is then transfer to the female cone. The ovule developed into the seeds after fertilization and the ovary develops into fruits.

How is a virus different from a bacterum?​
I am Lyosha [343]

(it would be helpful if you marked me as brainliest)  :)

Answer:

Viruses are tinier than bacteria. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.

16.Globular proteins fold up into compact, spherical structures that have uneven surfaces. They tend to form
nataly862011 [7]

Answer:(a)elastase

Explanation:

Elastase is a protease enzyme the function involves the cleavage of peptide bonds after amino acids with small side chains. This is responsible for cleaving the peptide bonds between the elastin fibers and aids in digestion of the elastic protein.

Thus the elastase cleaves the protein fibers this can be said that the elastase is a non-fibrous protein.
